Giants' Steve Smith injured in practice

New York Giants wide receiver Steve Smith will undergo tests after being injured while extending to make a catch in practice Thursday.

"Steve Smith went for a ball today and strained -- what they are calling right now -- is a strained pec," said head coach Tom Coughlin. "He had trouble driving his arm after the injury so he couldn’t continue. I don’t have anything to tell you about him until they do all of the tests."

If Smith's unable to go against the Cowboys, Mario Manningham would take his place in the starting lineup. Duke Calhoun would also receive more reps at wide receiver.

We'll keep you posted if there are any updates on Smith's injury. Smith has emerged as one of the most reliable receivers in the division, and the Giants' offense would be seriously compromised if he has to miss more than a game or two.
